Default Sneek Peak Of Prototype PRC Castings INSIDE!!

Guys here's a few pics of the all new Precision Race Components cathedral port cylinder heads. Sorry for there being so few pics, but I'll hold most the pics & specs for when the final version is completed.

We're currently working on several different versions of the heads but past that I can't really give any additional information.

Here's what I can tell you:

.800" thick deck!!
Modified Valve Angles
Better Than Stock p/v on some port configurations!
Multiple Port Options
Multiple Chamber Options
6 Bolt Upgraded!!
356-T6 Aluminum Casting

Designed & Built completely to our specs!

We're currently testing various versions of these cylinder heads on several different applications.

Sorry I can't give any additional information currently.

All I can say is I think you guys will really like the flow/features/pricing of this cylinder head!

Thats awesome...thats going to be great for your business and sales....

I know you're going to get a million questions on these...but I'll start with some simple ones.


1) Will these hopefully work with factory style valvetrain?

2) Are these going to be made in a broad enough range of arrangements to meet the needs of a healthy 346" motor and a 454" LSx setup ?
